Just switched from 10.04 to 11.10. I'm wondering about the limited options in the GUI for managing users and groups. Where is the old GUI to change groups, id's, etc. I know that I can do this from cli, that's no problem. But I want this comfortable GUI back.

With PolicyKit. (But default, PolicyKit is not present on Ubuntu Server systems.)

This power is conferred to users by membership in the appropriate group.

In Ubuntu 11.10 and earlier, administrators are members of the admin group.

In Ubuntu 12.04 LTS and later, administrators are members of the sudo group.

There are a couple complexities:

The sudo group exists in 11.10 and earlier, it's just not used (by default).

The admin group doesn't exist on a freshly installed 12.04 system, but it continues to exist (and its members continue to have administrative abilities) on Ubuntu 12.04 systems upgraded from previous releases.

Therefore, here are some reasonable guidelines for how to make a user an administrator in Ubuntu:

If you're running Ubuntu 11.10 or earlier, just put the user in the admin group.

If you're running Ubuntu 12.04 LTS (or later), put the user in the sudo group, and if the admin group exists, put the user there too.

You have a few options for managing users and groups.

Install and Run the Classic "Users and Groups" Utility

You'll perhaps be happy to hear that (as John S Gruber has pointed out) the old GUI utility for managing users and groups still exists, though you may have to install the package that provides it. I'm talking about the utility that was invoked in menu-driven interfaces via System > Administration > Users and Groups.

This classic utility is provided by the gnome-system-tools package, which you can install in the Software Center by clicking that link, or in the Terminal by running these commands:

sudo apt-get update
sudo apt-get install gnome-system-tools

The name of the Users and Groups utility is users-admin, so you can find it normally in your graphical interface, or you can run it manually with that name. That is, here are some ways to run the utility once it's installed:

Press Alt+F2. Type users-admin. Press Enter.

Press Ctrl+Alt+T. Type users-admin. Press Enter.

In Unity, start to type users and groups. So long as gnome-system-tools is installed, the Users and Groups utility will come up.

If you use a desktop environment that has menus, find Users and Groups in the Administration, System Tools, or Preferences menu.

On some Ubuntu variants, such as Lubuntu, users-admin is already installed and is the standard way to manage users and groups.

Use GNOME Control Center to Manage Users and Groups

The new, standard way to manage users and groups is with the GNOME Control Center, accessible from the session menu. Click the gear icon in the top panel (at the upper-right corner of the screen), and click System Settings....

In System Settings (also called the GNOME Control Center), click User Accounts (it's near the bottom, in the "System" category).

You can then manage users, including what groups they're members of, with this part of the GNOME Control Center.

Use Command-Line Utilities

If you...

are running Ubuntu Server, or some other Ubuntu system with no GUI, or

just prefer to use command-line utilities, or

are running some weird desktop environment that doesn't come with a graphical utility to manage users and groups

...then you can manage users and groups from the command-line.

The recommended utility for adding a user from the command-line (in Ubuntu, and also in Debian and other Debian-based OSes) is adduser. The simplest way to use it is just to run:

To make a user an administrator from the command-line, just add them to the appropriate group. usermod is an excellent utility for this purpose. The -G flag means you're specifying one or more new groups, and the -a flag means you're adding these to whatever groups the user is already a member of, rather than replacing the old list of groups with a new one.

Depending on what version of Ubuntu you're running (as detailed above), use one or both of these commands:

That "User Accounts" seems so limited. I need to add an account to a user-group. There existed "Users and Groups" before. I may do this job in terminal, but wanted to know where the menu is.

@Chang AFAIK that menu was taken out of the default install. But now that I know better what you're looking for, I did a quick search and updated my answer. Let me know if this looks more like what you want.

I don't know how limited this new "User Accounts" Ubuntu GUI is (I'm still using 10.10), but I can understand why they removed Gnome's "Users and Groups": the groups listed in the checkboxes (in Advanced Settings) are hardcoded and terribly outdated. Not to mention the selection for an "Administrator User" is quite different from Ubuntu's defaults for the first user.

The "user accounts" is just plain WRONG ubuntu has dumbed down the settings pannel way to far so users wont hurt them selves. If they are going to make a control pannel for dummies they need to add in a switch or other simple method for power users to get access to the normal controls with out having to install 100 normal and expected default tools

@Kendrick AFAIK the GNOME project should be blamed, not Ubuntu. Ubuntu just inherits whatever GNOME decides upstream, with a few exceptions. This is just one of the changes that was necessary to make the transition to GNOME 3.

For adding and deleting standard and administrative users I'd recommend that you use the standard tool Alex mentioned in his helpful answer. You will need to unlock the program and then click on the "+" on the bottom left. You can also administer passwords with this tool.

If you need to add groups or add users to groups you can install the gnome-system-tools package.

After adding that you can find the additional settings by searching the dash for Users and Groups
